Solar car sunshading and cooling device

Abstract

The invention relates to a solar car sunshading and cooling device which comprises a mechanical air-conditioning compressor originally arranged on the car and a car refrigerating circuit consisting ofa condenser, a condensing drier, an expansion valve and an evaporator which are communicated in sequence, and is characterized by also comprising an electric air-conditioning compressor with power supplied by a solar panel, wherein the electric air-conditioning compressor is communicated with the car refrigerating circuit, namely, two air-conditioning compressors are both connected with one set of refrigerating system, and the solar panel is installed on the top of the car. By utilizing solar energy to provide auxiliary refrigerating electric power, when one of the two air-conditioning compressors works, the refrigerating effect can be achieved, and especially when the car is parked, an energy consumption-free scheme is provided for reducing the temperature in the car; in addition, the solar panel installed on the top of the car can also play the role of sunshading.

Description

Technical field: [0001] The invention relates to a sun-shading and cooling device for solar automobiles, which can not only use solar panels for sun-shading, but also use solar power for cooling. Background technique: [0002] Shading cars in the open air in summer is a headache. Although there are various awnings or parasols, although they have certain sunshading efficiency, they still cannot effectively control the temperature rise inside the car. [0003] In fuel vehicles, it is a good way to install solar air conditioners. This direction can also be seen from the Chinese Patent Bulletin. A comprehensive analysis of the technical solutions for using solar energy to cool down is roughly as follows: one is to use semiconductor refrigeration technology, and the other is to use semiconductor refrigeration technology. It is to increase the refrigeration system such as the electric air-conditioning compressor, and the third is to increase the electric motor to drive the mechani...

Problems solved by technology

The first method requires more electricity due to the low efficiency of the existing semiconductor refrigeration, and the existing solar battery power supply capacity is limited, so the cooling effect is not ideal; the second method also needs to add additional condensers, evaporators, and fans Refrigeration components, such as complex structure and high cost; the third method, using the motor to drive the mechanical compressor, requires that the motor and the compressor have a relatively specific position on the engine, and a clutch should be set to control the clutch, which requires a lot in the spatial layout of the engine. leave a certain space, complex structure
